JOHN-E. HOI/VARD, OF READING, MASSACHUSETTS, FOR HIMSELF AND ASADMINISTRATOR OF CLARENCE E. HOWARD, DECEASED.

WIRE-BRUSH MACHINE.

SPECIFICATION forming part of Letters Patent No. 2546355, dated March7,1882. Application filed August 26, 1878.

To all whom it may concern Be it known that JOHN E. HOWARD and CLARENCEE. HOWARD, of Reading, Massachusetts, did invent an Improvement inWire.- Brush Machines; and I do hereby declare, on my own behalf and asadministrator of said CLARENCE E. HOWARD, now deceased, that thefollowing is a specification thereof.

The invention relates to certain improvements in machines for settingthe teeth or pins in the rubber or flexible material used in themanufacture of wire brushes; and the invention consists in a novelconstruction of devices and combination of parts, hereinafter fullydescribed and set forth.

Referring to the drawings, Figure l represents a front elevation of amachine embodying my improvements,with a portion removed in order moreclearly to show the working of several features of my invention. Fig. 2is a side elevation of the machine with a portion of the frame removed.Fig. 3 is a top or plan view. Figs. 4, 5, and 6 are enlarged views, indetail, of separate portions of the machine. Fig. 7 is a side, and Fig.8 a plan, view of the pin feeding and inserting devices.

Similar letters indicate like parts in the several figures. V

A A represent the frame of the machine. Within the frame Ais mounted inguides C C a vertically-moving carriage, B, tothe top of which isattached a cord, 0, passing over'pulleys b b, and having at its lowerend a counterbalance, a.

In front of the upper end of the carriage B is mounted in bearings d d acylindrical bar or rod, D, having a screw-thread cut on a portion of itslength, as shown in Fig. 1.

Upon the screw-rod D is supported a carriage, F, by means of bearingsff, provided each with a female screw fitting upon the screw of rod orbar D, so that as the latter turns or is rotated a lateral motion willbe imparted to the frame F. The lower end of the frame F is attached bymeansof bearin gs f f to a rod, D, upon which it moves freely, the rod Dbeing attached to the carriage B, as shown in Fig. 1.

Upon one end of the screw-rod D is secured a wheel, E, to be providedwith one or more notches, in which the end of a springedtch, 2,

attached to the carriageB, engages, so as to hold the screw-rod, D inplace. The rotation of the screw-rod D causes the frame to movelaterally, and the amount of motion governed by the notched wheel E andspring 0 is adapted to the required distance between the teeth to be setin the rubber back G. Within the frame F is secured the rubber back G,its lower end being fastened in a fixed clamp, g, and its upper end in aclamp, g, that moves up anddown within the frame F. At the rear of theclamp gis an ear, in which is fitted a thumb-screw, H, by which theclamp is moved up to tighten the rubber back G when necessary.

To the upper portion of the frame F is attached a rod or pointer, h,extending upward to an index, i, on which are marked a series ofrectangular lines to indicate the points of insertion of the wire teethin the back G.

The mode of elevating the frame or carriage B to admit of the insertionof the vertical rows of wire teeth is as follows: i

To the lower portion of the carriage B, at one side, is attached theflat bar I, having ratchetteeth on both edges, as shown in Fig. 1.

At one side of the ratchet-bar I is arranged the elevating-pawl l, whichis hinged to a flat bar, K, (shown in Figs. 1 and 4,) and which said baris also hinged to the inclined bed'or table L, secured within the mainframe A. In the center of the table L is a longitudinal recess orgroove, S, in which moves a sliding bar, S, attached to a slottedpitman, R, which in turn is hinged to the rock-shaft P, Figs. 2 and 4..At the end of the sliding bar S is a wedge-shaped projection, s,- which,as the said bar moves backward and forward, serves to raise the pawl l,which in the forward movement engages with and elevates the IfttCbQh-btlI and with it the carriage B.

The pawl l is operated by means of the plate M, apin on which passesthrough a slot in pawl l, and the plate or armMis connected at nearly aright angle with an arm or plate, N, which is hinged to the table L atn, Fig. 4. The arm or elbow M N is moved forward and back by means of arod, 0, provided with the adjusting-nuts O O, by which the motion of thehinged arm N is limited; The rear end of the rod 0 termin'ates'in a loopor slot, 0', in which 100 plays a screw-pin, p, fixed in the rocking barP, which latter is pivoted to the frame A at Q at its lower end, and atthe upper is hinged to a pitman, U, connected to the horizontallyslidingframe V.

The ratchet-bar I, and with it the frame or carriage B, is held up by apawl, T, hinged to the table L, and made to engage with the teeth ofratchet-bar I by means of a spring placed under a rectangular arm ofpawl T. By simply pressing down the rectangular arm the pawl T isreleased from the ratchet-teeth of bar I.

In the upper portion of the main frame A is a horizontal slidingcarriage, V, mounted in guides or supports V V, attachedto frame A.

To the center of the rear bar of frame V is attached the needle-bar w,holding the needle W by means of an adjusting-screw, w. The object ofthe needle is to perforate the rubber back G for the insertion of thewire teeth. To the center cross-piece, A, of the frame A is attached ashoe or guide, 22, (shown in Fig. 2,) which consists of a metal plateturned up at each side to form a groove, at theend, which comes incontact with the rubber back and serves as a guide orbearing to receivethe ends of the wire teeth as they are forced through the back G.

In front of the rubber back G is placed a trough or guide, y, whichreceives the wire teeth as they drop from the conducting-tube 6. At theend of the trough y is a spring, 2, held by a finger, 23, attached tothe table 24, for the purpose of retaining the wire teeth in position toinsure their proper insertion in they back G.

To the front of the frame V, and pointing inward, is attached a bar, :0,which constitutes the driver to force the wires into the back G from thetrough y. The driver :r is on a line with the needle W, and as theneedle moves back after piercing the back Gthe driver forces the wireinto the hole made by the needle.

The teeth used for the brush consist of short pieces of wire providedwith heads, and are fed to the machine as hereinafter described.

It represents a hopper in the form of a rectangular box, and having anarrow slit in the bottom, as indicated in Fig. 3, so as to allow theheaded wires to drop into and be held by the head. Within the hopper isa curved plate, m, extending from the top to the bottom of the hopper,and having an opening at the bottom sufficiently large to allow theheads of the wires to pass through. The object of this plate is toprevent the nails from cloggin g the exit of the hopper. The hopper kismounted on the trough 2, which latterforms the upper part of the racewayfor the wires. The trough 2 is supported on a standard, 16, at theelevated end and pivoted to a standard, 18, at the depressed end.

In the top of standard 16 are slots 17, Fig. 3, through which passscrews or pins in a plate, 19, attached to the under side of the trough2,

' so as to admit ofalateral motion of the trough and hopper to agitatethe wires, so as to cause them to pass into the trough. Extendin gdownward from the plate 19, and of which it forms a part, is a bar, 20,the lower end of which enters an angularslotin the bar2l,Fig. 5, whichlatter is attached to the sliding frame or carriage V, so that as thelatter traverses back and forth a vibratory motion will be imparted tothe hopper and the raceway, through which the headed wires pass.

Q is a trouglnwhich forms the upper portion of the raceway, the lowerportion, 3, being without sides, so as to allow the wires whose endshave not entered the raceway to drop off at the sides. At the lower endof the raceway 3 is a plate, 10, Fig. 2, arranged to allow of the escapeof only one wire at a time.

To the side of the raceway 3 is hinged a finger, of the form shown inFig. 6, the opening between the curved ends 7 8 of which corresponds tothe opening at the end of the raceway.

6 is a tube attached to the end of the raceway for receiving the wiresor teeth and conducting them to the trough y.

The curved ends 7 and 8 are caused to move to and fro across the end ofthe raceway, the pointed end 7 taking out one wire and the blunt end 8immediately closing the passage to prevent the escape of the wires untileach preceding one is disposed of. The finger 4 is pressed out from theraceway by a spring, 9, so as to hold the point 8 over the opening ofthe raceway.

To the outer forward end of the finger 4 is attached a shipping-bar, 11,extending downward to the level of bar 13. The bar 13 is supported in aslotted standard, 15, Fig.3, through which it moves freely. In one endof the bar 13 is a slot, 14, through which passes a screw attached tothe sliding carriage, by the movement of which latter an intermittentmotion is imparted to the bar 13.

On the bar 13 is placed a diamond-shaped shipping-block, 12, so arrangedin relation to the shipping-bar1lthat as the bar 13 is moved forward andback by the motion of carriageV the arm 11 will pass on one side of theblock 12 in one direction, causingthe finger 4 to move so as to carrythe point 7 across the end of the raceway 3 and remove a wire from thesame, and when the bar 13 moves in the opposite direction theshipping-bar 11 will pass along the other side of the block 12, and thusretract the finger 4,bringing the point 8 across the end of the racewayand preventing the escape of the wiresfrom the same. The relation of thefinger 4. to the spring gis adjusted by the screw 5.

The machine is put in operation by any suitable power applied to thecarriage V.

What Iclaim as the invention, and desire to secure by Letters Patent,is-- 1. The combination, with the sliding carriage F, of the adjustablesliding clamp g and ghumbscrew H, as and for the purpose set orth.

2. In awire-brush machine, the combination of the needle W and thedriver as, each attached to opposite ends of a moving carriage, the shoeor guide 22, and the trough 1, all arranged and operating as and for thepurpose set forth.

.chine, of the carriage B,the ratchet bar I, and

the pawls l and T, as set forth.

5. The combination of the recessed plate S, the sliding bar 8, theangular plate M N, the rod 0, and the rocking bar P, all arranged foroperating the intermittently-elevating pawl l, as set forth.

6. The combination, with the finger 4, of the bar 11, the shipping-block12, and the slotted bar 13 14, operated by the sliding frame V, as andfor the purpose specified.

7. In a wire-brush machine, the combination, with the hopper k andraceway 2 3, of the standards 16 18, the bar 20, and theangularlyslotted bar 21, operated by the carriage V, for imparting anoscillating motion to the hopper and raceway, as set forth.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.
